Do not pre-shrink any of the polyester battings. The polyester battings
will not shrink. “Dream Cotton” is the only cotton brand
which doesn’t need pre-shrinking.
Also, if you want a puckered antique look don’t pre-shrink.
To pre-shrink fill a washing machine with tepid water. Completely wet
the batting then spin out the excess water and either hang to dry on
a drying rack or dry on a low temperature in the dryer. Note: Pilling
may occur if a dryer is used.
